Detailed description of the invention
Below in conjunction with drawings and Examples, the present invention is described in further details.
As shown in Figure 3 and Figure 4, inner panel windowsill brace panel structure 1 of the present invention is located at windowsill 3 lower frame and is fixedly connected with in inner panel 2, comprise and protrude step surface 11, from the upper welding edge 12 that described protrusion step surface 11 extends toward windowsill 3 direction, from the side plate 14 that described protrusion step surface 11 is fixedly connected with described inner panel 2 toward the lower welding edge 13 that windowsill 3 opposite sense extends with protrusion step surface 11 both sides, it is characterized in that: described lower welding edge 13 is zig-zag, the every toothed rack of described lower welding edge 13 is provided with the solder joint welded with described inner panel 2, described lower welding edge 13 remainder trimming and described inner panel 2 are from sky.
This kind of structure, only overlaps in the position and inner panel 2 of arranging solder joint, clearly knows position of weld when workman can be allowed to weld, improve the stability of welding, provide work task efficiency; Give part loss of weight simultaneously, reduce costs.Lower welding edge 13 remainder trimming and inner panel 2, from sky, make electrophoresis liquid to enter smoothly, solve cannot enter electrophoresis liquid cause cannot be antirust problem, loss of weight strengthens rustless property simultaneously, improves the band Line stiffness of inner panel 2.
Described protrusion step surface 11 is vertically arranged, parallel with inner panel 2, and described lower welding edge 13 Z-direction is preferably dimensioned to be 13mm ~ 15mm, compared with prior art, increases inner panel 2 and the cavity body structure of inner panel windowsill brace panel structure 1, improves interior strip Line stiffness further.
Described upper welding edge 12 is also set to zig-zag, described upper welding edge 12 tooth bar is provided with the solder joint welded with described inner panel 2, do engrail, only overlap in the position and inner panel 2 of arranging solder joint, clearly position of weld is known when workman can be allowed to weld, improve the convenience of workman's welding, work efficiency improves; And make electrophoresis liquid to flow into smoothly and to discharge, loss of weight strengthens rustless property simultaneously.
Described protrusion step surface 11 is provided with lightening hole 112, also can first be provided with concave surface 111 at protrusion step surface 11, described concave surface 111 arranges lightening hole 112 again.Lightening hole 112 is played at the positive pressing direction of described protrusion step surface 11, the air of cavity between inner panel 2 and inner panel windowsill brace panel structure 1 can be discharged, electrophoresis liquid can fully be attached to panel beating housing surface, improves the rustless property of part, gives part loss of weight simultaneously.
Described concave surface 111 extends along described protrusion step surface 11 length direction, and the average layout of described lightening hole 112 is on described concave surface 111, and preferred described concave surface 111 bottom surface is measure-alike with lightening hole 112, like this rigidity of increase protrusion step surface 11 entirety.
